//1 使用axios前置拦截器，让所有的请求都携带token
//=============axios的前置拦截器==========================//
//作用：每次发送axios请求之前都要执行这个业务

    //携带token
    let token = localStorage.getItem("token");

        config.headers['U-TOKEN'] = token;

//2 使用axios后置拦截器，处理没有登录请求
//=============axios的后置拦截器==========================//
//作用：专门处理axios响应回来的数据。先于回调函数执行
axios.interceptors.response.use(result => {
    let data = result.data;
    if (data.code === 401 && data.message === "noLogin") {

        router.push('/noPer');
    }
    return result;
}, error => {

})

//======================静态资源拦截器/路由拦截器【拦截不到后端或不发送axios请求的请求】====================//

//处理页面刷新动态路由失效问题
